Items described below to understand them before doing service work. IMPORTANT NOTICE Changes may have been made to this copier to improve its performance after this Service Manual was printed. Accordingly, Minolta Corporation, makes no representations or warranties, either expressed or implied, that the information contained in this Service Manual is complete or accurate. It is understood that the user of this Service Manual must assume all risks or personal injury and/or damage to the copier while servicing the copier for which this Service Manual is intended. Therefore, this Service Manual must be read carefully before doing service work both in the course of the technical training and even after that, for keeping the correct maintenance and control of the copier. Keep this Service Manual also for the future service. When it is impossible to read the description about safety and warning (due to contamination or tear), the relevant page should be replaced. DESCRIPTION ITEMS FOR DANGER, WARNING AND CAUTION In this Service Manual, each of three expressions, " DANGER", " WARNING" and " CAUTION" is defined as follows together with a symbol mark to be used in a limited meaning. When servicing, the relevant works (disassembling, assembling, adjustment, repair and maintenance) need to be conducted with utmost care. DANGER: WARNING: CAUTION: Actions having a high possibility of suffering death or serious wound Actions having a possibility of suffering death or serious wound Actions having a possibility of suffering a slight wound, medium trouble and material damage C-1 SAFETY AND IMPORTANT WARNING ITEMS SAFETY WARNINGS [1] MODIFICATIONS NOT AUTHORIZED BY Minolta Minolta copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Photocopier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have to be taken into consideration, with the aim of arriving at proper tolerances and safety factors. For this reason, unauthorized modifications involve a high risk of degrading performance and safety. Such modifications are therefore strictly prohibited. The points listed below are not exhaustive, but they illustrate the reasoning behind this policy. PROHIBITED ACTIONS : (1) Using extension cables or a different power cord than specified by Minolta. (2) Using other fuses than specified by Minolta. Safety will not be assured, leading to a risk of fire and injury. (3) Disabling fuses or bridging fuse terminals with wire, metal clips, solder or similar. (This applies also to thermal fuses.) (4) Removing air filters (except for replacement). (5) Disabling relay functions (such as wedging paper between relay contacts, etc.). (6) Disabling safety functions (interlocks, safety circuits, etc.). Safety will not be assured, leading to a risk of fire and injury. (7) Performing actions to copier not described in the instruction manual or the service handbook. (8) Using parts other than specified by Minolta. 1. Advance Preparation for Safety Checks CAUTION: (1) Wear clothing that facilitates work and is designed for safety. (2) Carry out all procedures carefully to prevent injury. (3) Be sure to disconnect the power cord of the copier and all optional equipment from the AC outlet. Simply turning off the power switch is not sufficient, because paper feed units or other electrical equipment may be powered also when the power switch is turned off. (4) Proceed with special care when performing operation checks or adjustment while the unit is powered. When carrying out operation checks or adjustment while external covers are removed, the risk of electrical shock exists when touching parts which carry high voltage or electrical charge. The risk of injury exists when touching moving parts such as gears or chains. 2. Safety Checkpoints The following list is not exhaustive, but it includes actions which must be carried out at every on-site service. CAUTION: (1) Check external covers and the frame for sharp edges, burrs, or nicks. (2) Check external covers and hinges for loosening or damage. (3) Check wiring for squeezing or damage. (4) Check power cord for insulation problems (conductor must not be exposed). (5) Check power cord and cable ties etc. for loosening from frame. WARNING: (1) Verify that the copier is properly grounded. If a problem is detected, establish a proper ground connection. (2) Connecting the ground lead to an improper point such as listed below results in a risk of explosion and electric shock. Unsuitable ground points: - Gas pipe - Lightning rod - Telephone line ground - Plastic water pipe or water pipe or faucet that has not been approved by authorities for grounding use [2] CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE Minolta copiers are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect the customer and customer engineer from the risk of injury. However, in daily use, any electrical equipment may be subject to parts wear and eventual failure. In order to maintain safety and reliability, the customer engineer must perform regular safety checks. C-2 SAFETY AND IMPORTANT WARNING ITEMS 3. Description of Safety Checks (1) CAUTION: Before performing safety check work, read all relevant documentation (Service Manual, technical notices, etc.) and proceed according to the prescribed procedure, using only the prescribed tools. Do not carry out any adjustments not described in the documentation. If the power cord is damaged, replace it only with the specified power cord. If the power cord insulation has been damaged and there are exposed sections, short- circuits and overheating may occur, leading to a serious fire risk. Do not route the power cord so that it can be stepped on or pinched. Otherwise overheating may occur, leading to a serious fire risk. When disconnecting any cables, always grasp the connector and not the cable (especially in the case of AC and high-voltage leads). Carefully remove all toner remnants from electrical parts, electrodes, etc. Make sure that wiring cannot come into contact with sharp edges, burrs, or other pointed parts. Double-check to make sure that all screws, components, wiring, connectors, etc. that were removed for safety check maintenance have been reinstalled in the original location. (Pay special attention to forgotten connectors, pinched cables, forgotten screws, etc.) When installation and preventive maintenance, verify that the power cord has been securely plugged into the AC outlet. Contact problems may lead to increased resistance, overheating, and the risk of fire. [3] HANDLING OF MATERIALS FOR SERVICING CAUTION: Drum cleaner (alcohol-based) and roller cleaner (acetone- based) are highly flammable and must be handled with care. When using these materials for cleaning of copier parts, observe the following precautions. Disconnect the power cord from the AC outlet. Use only a small amount of cleaner at a time and take care not to spill any liquid. If this happens, immediately wipe it off. Perform cleaning only in an environment where sufficient ventilation is assured. Breathing large quantities of organic solvents can lead to discomfort. Do not replace the cover or turn the unit on before any solvent remnants on the cleaned parts have fully evaporated. CAUTION: Toner and developer are not harmful substances, but care must be taken not to breathe excessive amounts or let the substances come into contact with eyes etc. It may be stimulative. If the substances get in the eye, rinse it with plenty of water immediately. When symptoms are noticeable, consult a physician. (2) (1) (2) (3) (3) (4) (4) (5) (6) (7) [4] CONCLUSION (1) Safety of users and customer engineers depends highly on accurate maintenance and administration. Therefore, safety can be maintained by the appropriate by the proper daily service work conducted by the customer engineer. (2) When performing service, each copier on the site must be tested for safety. The customer engineer must verify the safety of parts and ensure appropriate management of the equipment. (8) WARNING: (1) Before disassembling or adjusting the write unit or any parts that use a laser, make sure that the power cord has been disconnected. (2) Do not remove the main cover of the write unit. Direct exposure of the eye to laser beams may lead to blindness. (3) Do not turn the copier on while the write unit is not installed in its normal position. (4) Danger of explosion if battery is incorrectly replaced, replace only with the same or equivalent recommended by the manufacturer. Discard used batteries according to the manufacture's instructions. VORSICHT: (4) Expiosionsgefahr dei unsachegemäßem Austausch der Battetie. Ersatz nur durch denselben oder einen vom.

Check whether the installation environment is good. a. The machine must be installed in a properly ventilated area not exposed to high temperature, high humidity, and direct sunlight. b. The machine must be installed on the horizontal floor. Check whether original has a problem to cause the defective image. Check whether the selected density value is correct. Check whether the surface of the platen glass and the bottom of the RADF are clean. Check whether correct paper is used for copying. Check whether copying materials and parts (e.g., developer, drum, and cleaning blade) are replenished and replaced when they reach the end of the useful life. Check whether toner remains. 4. 5. Take care not to damage the drum with tools and so on. Do not touch IC pins with bare hands. 4. 5. 6. 7. 8. 9. 10. When servicing the machine, observe the following precautions: 1. Only either side of the AC line is shut off when the main power of this machine is turned off. Always unplug the power cord before starting the service work. If it is necessary to service the machine with the power on, take care not to be caught in the scanning gear of the exposure unit. Special care should be taken when handling the fixing unit because it operates at extremely high temperatures. The developing unit has a strong magnetic field. Keep watches and measuring equipment away from it. 2. 3. 1-1 1 ADJUSTMENT 1 ADJUSTMENT ADJUSTMENT ADJUSTMENTS MADE WHEN REPLACING PARTS Adjustments (including checks) and settings are not only required when a customer complaint about the copy image quality is received, but also after replacing or reassembling parts.

Cautions: Printer control board replacement precautions · When a damaged image control board is replaced, the memory board on this board must be used on the new image control board. Only when the memory board is also damaged, use a new memory board on a new control board. Since the new memory board does not have adjustment data, the above adjustments are required. Before making the above adjustments, make the "47-92(output)" setting to make the new memory board effective. · After making any adjustment, make the "47mode-96(output ) setting" . After made the "47mode96(output )" setting, the adjustment data is saved. · However, the "47mode -92" and -96" settings are protected to prevent them from careless operation. In order to make "47mode -92" and -96" settings using the saved adjustment data, the protection must be disabled. For the unprotection method, contact the service manager of the authorized distributor.
